Let the Games begin! No, seriously, they actually can begin now that we have an official trailer with Lorde's official song for the upcoming The Hunger Games: Mockingjay Part 1! We knew Lorde was handling the entire soundtrack and have basically been playing "Yellow Flicker Beat" on repeat ever since we first heard it back in September. Now, it's safe to say we'll be watching this 60 second TV spot (entitled, "Return to District 12," where Katniss is shown doing just that) over and over and over again until November 21.
